Fatal Error on log in [FTB Infinity Lite 1.10]

When trying to log into the FTB infinity server, I immediately am disconnected with the message "A fatal error has occurred, this connection is terminated".

I was originally disconnected while I was traveling around the map, making me think the error is due to the chunk I was entering being bugged in some way, however, reducing my render distance down to 2 chunks didn't seem to let me online.

I think that this could potentially be fixed by teleporting me to spawn, such that I can connect? I'm not sure.
